BackgroundThe relationships between dietary fiber, whole grains, carbohydrate, glycemic index (GI), glycemic load (GL), and prostate cancer risk are unclear. We conducted a systematic review and meta-analysis to investigate these associations.MethodsRelevant studies were identified by a search of PubMed database and EMBASE database up to April 2015. A random effects model was used to calculate the summary relative risks (RRs) and their corresponding 95% confidence intervals (CIs).ResultsTwenty-seven epidemiological studies (18 case–control studies and nine cohort studies) were included in the final analysis. The pooled RRs of prostate cancer were 0.94 (95% CI 0.85–1.05, P=0.285), 1.13 (95% CI 0.98–1.30, P=0.095), 0.96 (95% CI 0.81–1.14, P=0.672), 1.06 (95% CI 0.96–1.18, P=0.254), and 1.04 (95% CI 0.91–1.18, P=0.590) for dietary fiber, whole grains, carbohydrate, GI, and GL, respectively. There was no evidence of significant publication bias based on the Begg’s test and Egger’s test.ConclusionThe findings of this meta-analysis indicate that, based on available information, dietary fiber, whole grains, carbohydrate, GI, and GL are not associated with the risk of prostate cancer.
The present study aimed to retrospectively analyze the safety and efficacy of the early surgical management of thoracic tuberculosis (TB) in patients with neurological deficits. The medical data of patients with thoracic TB exhibiting neurological deficit in the Chest Hospital of Hebei Province were retrospectively reviewed. A total of 234 cases, including 123 males and 115 females, were recruited in the present study. Their pre- and postoperative neurological deficit and pain levels were assessed using the 2002 American spinal injury association (ASIA) impairment scale and visual analog scale, respectively. Patients were divided into two groups according to whether their preoperative standardized anti-TB treatment time was ≥4 weeks or <4 weeks. There was no difference in blood loss and operation time between the two groups. The erythrocyte sedimentation rate was higher in patients receiving standard anti-TB <4 weeks prior to and 1 month following surgery compared with the ≥4 weeks group, but the difference was not significant 6 months following surgery. ASIA scale scores all increased significantly 1 month following surgery in the <4 weeks group compared with the ≥4 weeks group (P=0.001) though there was no difference between the scores prior to surgery. ASIA scale scores improved to 4.4±0.5 and 4.5±0.4 in patients with anti-TB treatment times of ≥4 weeks and <4 weeks, respectively, 24 months following surgery (P=0.0895). The present study demonstrated that for patients with thoracic TB exhibiting neurological deficit, early surgical management following <4 weeks' standard anti-TB treatment is recommended. It may relieve spinal cord compression and also benefit the early recovery of neurological function in these patients.
While China's economic progress and social transformation demand an urgent refurbishment of its social welfare system, after a decade of development community centers have gradually become the major infrastructure of service delivery in urban China. In this article, the authors examine the social and historical context of the development of community services in urban China, and then focus on the community center as an emerging force in a society undergoing considerable change. A study of community centers in Jinan, a large city in eastern China, is reported, which reveals major difficulties that hinder the development of these centers as the principal hubs of community life. The authors outline the possible future directions of community service in China and, in particular, consider the role of community centers in the new social welfare sector of this nation.
Purpose The purpose of this study was to analyze long-term complications, urodynamics, and quality of life (QoL) of patients after orthotopic ileal neobladder with orthotopic ureteral reimplantation to enrich clinical data and provide a basis for clinical use of this surgery. Methods Between January 2007 and January 2013, 72 consecutive patients who underwent spiral ileal neobladder following radical cystectomy were enrolled. The neobladder was created using a modified Camey-II technique. Complications were reviewed and staged according to Clavien-Dindo classification and evaluated in long-term follow-up. Urodynamics were performed, and QoL was assessed by the Functional Assessment of Cancer Therapy for Bladder Cancer (FACT-BL) instrument. Results The total follow-up time was 60 months, and the total survival rates at 3 and 5 years after surgery were 76.4% (55/72) and 65.3% (47/72), respectively. There were 34 (47.2%) early complications in 23 (31.9%) patients and 42 (58.3%) late complications in 35 (48.6%) patients. The total satisfactory control rates were 69.1% and 66.0% at 3 and 5 years after the surgery, respectively. Urodynamic studies were performed in some patients, and the receiver operating characteristic curve analysis showed that pressure at maximum capacity, compliance, and post void residual urine had predictive value for mortality (P < 0.05). The total FACT-BL scores of patients at 1, 3, and 5 years postoperation were 125.0 ± 15.2, 127.0 ± 16.2, and 120.6 ± 13.5, respectively, and it decreased at 5 years postoperation (P < 0.05). Conclusion Spiral ileal neobladder with orthotopic ureteral reimplantation offers satisfactory long-term results, and urodynamic monitoring might have prognostic value.
Psychological distress and mental illness have become increasingly pervasive among Chinese university students. However, many university students who need mental health treatment or psychological support do not actively seek help from professional counselors or service providers, which could lead to poor mental health outcomes. To promote help-seeking, we undertook a qualitative study to understand Chinese university students’ perspectives on help-seeking and mental health counseling. We conducted 13 focus group interviews with students in six universities in Jinan, China, and altogether 91 (62%) female students, and 56 (38%) male students participated in the study. Our results indicate that students’ misconception and distrust of on-campus counseling, stigma of mental illness, low mental health literacy, and hard-to-access mental health services are the major barriers that impede students help-seeking behaviors. Internal struggles and systematic and organizational barriers are identified to shed light on future work to promote mental health literacy among Chinese university students.
This study aimed to explore the association between mental health knowledge level and the prevalence of depressive symptoms among Chinese college students. A cross-sectional study was conducted in six universities in Jinan, Shandong Province, China, and a total of 600 college students were recruited to self-complete a series of questionnaires. The Mental Health Knowledge Questionnaire (MHKQ) was used to investigate the level of mental health knowledge. Depressive symptoms were investigated with the depression subscale of the Depression Anxiety Stress Scale (DASS-21). The prevalence rate of depressive symptoms among college students was 31.2%. Compared with MHKQ scoring in the 1st quartile, college students with MHKQ scoring in the 3rd quartile and in the 4th quartile reported lower levels of depressive symptoms after adjusting for potential confounding factors. Since mental health knowledge level was related to depressive symptoms among college students, increased efforts to promote the level of mental health knowledge in Chinese college students are critical.
